闽江下游突发性水污染事故时空模拟

以闽江下游为例,基于有限元法建立闽江下游水动力模型及水质模型,通过对模型进行率定和验证,表明该模型具有较理想的模拟效果.在此基础上,利用闽江下游2004年的水文情况,模拟了突发性水污染事故中污染物的运移扩散过程.定量模拟了突发性水污染事故发生后,闽江下游不同地点处污染物到达的时间和浓度值,并对突发风险事故的影响范围、程...

Time-space simulation for sudden water pollution accidents in the lower reaches of the Minjiang River

Based on the finite element method, a hydrodynamic model and a water quality model for the lower reaches of the Minjiang River were established. After verification by coefficient calibration and model verification, the models were used for a real simulation. Using the established models, the diffusion and dispersion of pollutants in sudden water pollution accidents were simulated under the 2004 hydrological status These models can be used to quantitatively predict the time, area and concentration of pollutants in the lower reaches of the Minjiang river when pollution accidents occur.
